Initial draft version for 2010

IK2555 Wireless and Mobile Network Architectures is a 7.5 point course designed for advanced undergraduates and graduate students; especially those in the Telecommunication Graduate Program or the International Masters Wireless program.

Advanced undergraduates should have completed the course 2G1305/IK1550 (Internetworking) or 2G1701 (Advanced Internetworking) or an equivalent course. Students without one of these courses should obtain permission of the instructor.

Information is available on:


This course will give both practical and general knowledge concerning wireless and mobile network architectures. After this course you should have some knowledge of these architectures and understand the basic priciples behind them.

Learning Outcomes

Following this course a student should be able to:

  • Understand the architecture of existing mobile and wireless networks at a sufficient level to recognize the common features of such networks in any mobile or wireless network.
  • Based upon recognition of common features, the student should be able to compare and contrast one network architecture with another.
  • Describe differences between different types of mobility (such as user mobile, terminal mobility, session mobility) and understand how each type of mobility can be supported.
  • Understand the core network protocols and applications in third generation mobile networks.
  • Read the current literature at the level of conference papers in this area.
    • While you may not be able to understand all of the papers in journals, magazines, and conferences in this area - you should be able to read 90% or more of them and have good comprehension. In this area it is especially important that develop a habit of reading the journals, trade papers, etc. In addition, you should also be aware of both standardization activities, new products/services, and public policy in the area.
  • Demonstrate knowledge of this area both orally and in writing.
    • By writing a paper suitable for submission to conferences and journals in the area.

This course should prepare you for starting an exjobb in this area (for undergraduate students) or beginning a thesis or dissertation (for graduate students).


  • Telesys, gk or Datorkommunikation och datornät/Data and Computer Communications or equivalent knowledge in Computer Communications; Internetworking; and permission of the instructor

Students considering participating in this course should contact the instructor.


This course will focus on the network architectures that are used in wireless and mobile networks. In some cases we will dig deeper into the protocols used by such networks. The course should give both practical and more general knowledge concerning the these network architectures.

The course consists of 10 hours of lectures, and an assigned paper requiring roughly 50h of work by each student.

Examination Requirements

  • An assigned paper requiring roughly 50h of work by each student
  • Registration: Monday 08-Feb-10, to maguire@kth.se with the "Subject: IK2555 topics" giving:
    • Group members, leader.
    • Topic selected
  • Written report
    • The length of the final report should be ~10 pages (roughly 5,000 words) for each student; it should not be longer than 12 pages for each student - papers which are longer than 12 pages per student will be graded as "F".
    • The paper style should be that of a conference paper.
    • Papers should not focus on physical and link layer issues as this is not a course in radio communication systems, but rather the papers should look at things which have an impact on the architecture or upon which the architecture has an effect.
    • If there are multiple students in a project group, the report may be in the form of a collections of papers, with each paper suitable for submission to a conference or journal.
    • Contribution by each member of the group - must be clear (in the case where the report is a collection of papers - the role of each member of the group can be explain in the overall introduction to the papers.
    • The report should clearly describe: 1) what you have done; 2) who did what; if you have done some implementation and measurements you should describe the methods and tools used, along with the test or implementation results, and your analysis.
    • Final Report: written report due Sunday 07-Mar-10 at 23:59 + oral presentations scheduled during week 11 (15-19 March 2010) at Wireless@KTH (in the open area just as you enter the center). Note that the center is located on the 3rd floor of the Electrum 1 building near the C elevator (i.e., the north end of the bulding). The address of the building is Isafjordsgatan 22, Kista. However, the nearest entrance is labelled Isafjordsgatan 26. Note that the Kistagåen 16 entrance to the building is at the south end of the 3rd floor. I will try to schedule most presentation on Monday the 15th of March 2010.
    • Send email with URL link to maguire@kth.se
    • Late assignments will not be accepted. Papers which are submitted after the deadline will be graded, but the grading might not be completed before the end of the term.
    • Note that it is pemissible to start working well in advance of the deadlines!
    • Language: the report can be written in Swedish or English (NB: I can provide better feedback if the report is written in English.)
    • For your document, you should be sure to use A4 sized paper rather than US letter.
    • For those using LaTeX, you can improve the look of the document by:
      • switching to using PostScipt fonts (instructions)
      • You can also turn off hyphenation or at least limit its use with "\hyphenpenalty=5000 \tolerance=1000"
  • Oral presentations: Each group should present their results in 15 minutes or less. The presentation should not be more than 15 minutes, given the 20 minute timeslot this gives time for a couple questions and changing presenters. if there are multiple days of presentations, you only need to attend the day you present.


For new ECTS grading:

  • To get an "A" you need to write an outstanding or excellent paper and give an outstanding or excellent oral presentation. (Note that at least one of these needs to be excellent.)
  • To get a "B" you need to write a very good paper, i.e., it should be either a very good review or present a new idea; and you have to give a very good oral presentation.
  • To get a "C" you need to write a paper which shows that you understand the basic ideas underlying mobile and wireless networks and that you understand one (or more) particular aspects at the level of an average masters student. In addition, you must be able to present the results of your paper in a clear, concise, and professional manner - and answer questions (as would be expected at a typical international conference in this area.)
  • To get a "D" you need to demonstrate that you understand the basic ideas underlying mobile and wireless networks, however, your depth of knowledge is shallow and you are unable to orally answer indepth questions on the topic of your paper.
  • If your paper has some errors (including incomplete references) or you are unable to answer any indepth questions following your oral presentation the grade will be an "E".
  • If your paper has serious errors or you are unable to answer basic questions following your oral presentation the grade will be an "F".
  • If your paper or oral presentation are close to passing, but not at the passing level, then you will be offered the opportunity for "komplettering", i.e., students whose written paper does not pass can submit a revised version of their paper (or a completely new paper) - which will be evaluated; similarly students whose oral presentation is unacceptable may be offered a second opportunity to give their oral presentation. If a student fails the second oral presentation, they must submit a new paper on a new topic in order to give an oral presentation on this new topic.

Code of Honor and Regulations

It is KTH policy that there is zero tolerance for cheating, plagiarism, etc. - for details see http://www.kth.se/student/studentliv/studentratt?l=en_UK See also the KTH Ethics Policies

Some common flaws in reports

  • Incomplete references
  • Missing important citations
  • Statements made without justification or supporting citations
  • Poor (or no) editing
  • Failure to spell check the document
  • Documents which it is clear that no one looked at after formatting - often these have breaks in the middle of sentences, missing phrases, ... .
  • Lack of page numbers
  • Unreadable text in figures
  • Failure to label elements of figures adequately
  • Use of contractions
  • Use of acronyms or abbreviations without properly introducing them; often failure to use these acroynms and abbreviations consistently through the rest of the paper
  • Redundant text
  • Using figures from others without the copyright owner's permission
  • Using too few refences, so the paper looks like simply a cut an paste edit of these references.
  • Single sentence paragraphs
  • Lack of vertical white space between paragraphs, which in some cases makes it hard to understand where new paragraphs begin
  • Lack of a date - every document should have a date, in addition to title and author(s)
  • Lack of section, subsection, ... number - makes cross references difficult

Handsets poised to be commodities: "Microsoft, Intel Aim for High-End Phone", Wall Street Journal Europe, Tuesday, 19 Feb. 2002, page 1 and pg. A6, features an article, which describes how they are attempting to provide a platform for high-end phones so that they will be commodities just like PCs. The figure on A6 shows the basic components of a handset and lists the prices for the components and for licensing the design "framework":

color screen 17 euro
printed circuit board 9 euro
flash memory 2 euro
radio chip and related electronics 40 euro
baseband chip 34 euro
